Subsurface probe and hydrochemical analysis for the purpose of siting waste landfill
This paper deals with the probing of the subsurface by electrical resistivity method and hydrochemical analysis for the purpose of siting waste landfill. The landfill design made provision for secured containment of the segregated waste and associated leachate from man and industrial activities. The waste types that are disposed of in the landfill are mainly domestic and non-hazardous industrial wastes. The...

Spatial and temporal distribution of North Atlantic tropical cyclones
The aim of this work is to provide a classification of tropical cyclones (TC) according to their location, month of genesis and their lifecycles and to study the role of African Easterly Waves (AEWs) in North Atlantic cyclogenesis. Between 1980 and 2004, 269 tropical cyclones (TCs) were formed over the North Atlantic, 77% of which occurred during the August-October period and 95% of major hurricanes (TCs in...

Health and safety conditions of building maintenance sites in Nigeria: Evaluating the post occupancy contaminations of timber buildings by microorganisms
This research assessed the safety of the environmental conditions of timber buildings as maintenance sites from cultivable microorganisms under various climatic conditions in Nigeria. Several site illnesses leading to poor work and reduced productivity on construction sites have been attributed to unidentified microorganisms or their metabolites. To identify the microorganisms, bulk samples were collected on...

Cytogenotoxicity evaluation of two industrial effluents using Allium cepa assay
The cytogenotoxic effects of the industrial effluents from paint (0, 7.2, 18, 36 and 72%) and textile (0, 1.6, 4, 8 and 16%) manufacturing were evaluated using root tip cells ofAllium cepa. In this study, root length and chromosomal aberration assays were used to determine the 96 h effective concentration (96 h EC50), root growth inhibition, mitotic index and chromosome aberration rate. Based on the 96 h...

Reuse of wastewater in urban farming and urban planning implications in Katsina metropolis, Nigeria
Studies on urban farming in Sub-Saharan African cities reveal the existence of literatures in Eastern, Southern and Central African cities. A few have focused on West Africa. In Nigeria, there is a paucity of information on reuse of waste water in urban farming. The purpose of this paper is to examine the status of wastewater reuse in urban farming in Katsina, an important urban area in the semi arid region...

Geophysical mapping of the occurrence of shallow oil sands in Idiopopo at Okitipupa area, South-western Nigeria
Oil sands are known to be an alternate source of energy and of great economic value. To map the occurrence of shallow oil sand deposits in Idiopopo, Okitipupa area in Ondo state South-western Nigeria, vertical electric sounding (VES) in 11 stations along 3 profiles were carried out using the Schlumberger configuration. Apparent resistivity value obtained ranged from (135.7 ± 0.05) ohm-m to (4592.6...

Biotreatment of anthraquinone dye Drimarene Blue K2RL
Drimarene blue (Db) K2RL is a reactive anthraquinone dye, used extensively in textile industry, due to poor adsorbability to textile fiber; it has a higher exhaustion rate in wastewater. The dye is toxic, carcinogenic, mutagenic and resistant to degradation. Decolorization of this dye was studied in two different systems. Shake flask study, using the same immobilized fungus Aspergillus niger SA1 with increasing...
